Description

Technical Field

[0001] This application relates to the field of marine machinery, and more particularly to a cable winding machine. Background Technology

[0002] Cable winding machines are specialized equipment used for winding, sorting, and storing cables, and are widely used in shipbuilding, fishing, ports, construction, and rescue industries.

[0003] When a cable winding machine is in use, during the process from when the mechanical brake receives the braking signal to when it is fully engaged, the drum of the cable winding machine continues to rotate due to inertia, causing fluctuations in cable tension. The steel wires inside the cable are prone to micro-cracks due to tension fluctuations, which accelerates fatigue damage to the cable and thus shortens its service life. Summary of the Invention

[0004] To improve the service life of cables, this application provides a cable winding machine.

[0005] This application provides a cable winding machine, which adopts the following technical solution: A cable winding machine includes a body and a tensioning assembly connected to the body. The body has inlet and outlet holes on both sides, with the axes of the inlet and outlet holes parallel to each other. The tensioning assembly is located between the inlet and outlet holes. The tensioning assembly includes a tension roller one and a tension roller two, which are rotatably connected to the surface of the body at intervals. The axes of tension roller one and tension roller two are parallel to each other, and the axis of tension roller one is perpendicular to the axis of the outlet hole. Tension roller two is located between tension roller one and the inlet hole. The diameter of tension roller one is larger than the diameter of tension roller two. The cable passes through the inlet hole, sequentially winds around tension roller one and tension roller two, and exits from the outlet hole.

[0006] By adopting the above technical solution, the cable passes sequentially around tension roller one and tension roller two from the inlet hole and exits from the outlet hole. This requires the cable to undergo two directional changes during braking, instead of the diameter extending from the inlet hole to the load end. Simultaneously, the elastic deformation of the cable is distributed across the bending sections of tension rollers one and two, rather than concentrated at a single location, reducing the risk of localized stress concentration. Furthermore, the diameter of tension roller two is smaller than that of tension roller one, resulting in a smaller bending radius of the cable when passing over tension roller two. This leads to a greater normal pressure and friction at the contact surface between the cable and tension roller two, requiring the cable to overcome greater... Only with high static friction can the cable slide, thus limiting its initial speed. When the cable passes over tension roller one, its bending radius is large and the friction is relatively small, acting as a second-level constraint to further attenuate the cable's movement. The additional resistance provided by tension roller one prevents a sudden drop in tension, making the combination of tension roller one and tension roller two equivalent to a dual-mass damping system. This system can filter high-frequency tension fluctuations, ensuring a smooth transition of cable tension during braking. This also makes the steel wires inside the cable less susceptible to micro-cracks caused by tension fluctuations, reducing fatigue damage to the cable and extending its service life.

[0007] Optionally, the tension roller one and tension roller two are located on opposite sides of the inlet hole axis.

[0008] By adopting the above technical solution, tension roller one and tension roller two are located on both sides of the inlet hole axis, so that when the cable passes through the inlet hole, passes around tension roller one and tension roller two in sequence, and exits from the outlet hole, it forms a zigzag path. The cable needs to undergo two changes of direction during braking. This dual-direction design disperses the braking impact into two independent stages, avoiding concentrated and sudden changes in cable tension. At the same time, the layout of tension roller one and tension roller two on both sides increases the contact wrap angle between the cable and the two rollers, increasing the friction, thereby more effectively restricting the movement of the cable and further reducing the tension fluctuation of the cable.

[0009] Optionally, the tensioning assembly further includes multiple limiting rings, which are divided into two groups. The inner walls of the multiple limiting rings in one group are spaced apart and connected to the outer circumferential surface of tension roller one, while the inner walls of the multiple limiting rings in the other group are spaced apart and connected to the outer circumferential surface of tension roller two. The arrangement direction of the limiting rings is parallel to the axis of tension roller one, and the limiting rings on tension roller one and tension roller two are staggered in the arrangement direction. A limiting gap is left between two adjacent limiting rings for the cable to pass through, and the cable can pass through the limiting gap of tension roller one and the limiting gap of tension roller two in sequence.

[0010] By adopting the above technical solution, the two sets of limiting rings are staggered in the arrangement direction, so that the cable needs to pass through the limiting gap of tension roller one and the limiting gap of tension roller two in sequence to form an "S" shaped zigzag path. This disperses the inertial impact of the cable during braking to multiple limiting points, realizes the gradient adjustment of friction force, thereby suppressing the sudden change of cable tension and further improving the service life of the cable.

[0011] Optionally, the tensioning assembly further includes a driving gear, a transmission gear, and a driven gear. The driving gear is coaxially connected to both ends of the tensioning roller, the driven gear is coaxially connected to both ends of the tensioning roller, and the transmission gear is rotatably connected to the surface of the machine body. The transmission gear meshes with the driving gear and the driven gear.

[0012] By adopting the above technical solution, the driving gear is coaxially fixed at both ends of the tension roller, and the driven gear is coaxially fixed at one end of the tension roller, sharing the same axis of rotation. This avoids the need for additional bearings, couplings, or brackets required by the split design, and significantly reduces the production cost of the cable winding machine.

[0013] Optionally, the machine body includes a base, a guide column, and an adjusting block. The tensioning assembly is connected to the base, the guide column is connected to the base, the axis of the guide column and the axis of the tensioning roller are parallel to each other, the adjusting block is slidably connected to the surface of the guide column, the sliding direction of the adjusting block is parallel to the axis of the guide column, and the outlet hole is located on the adjusting block.

[0014] By adopting the above technical solution, the position of the cable outlet hole can be flexibly changed by driving the adjusting block to slide on the guide column, without the need to redesign or install a fixed cable outlet structure, thereby improving the ease of use of the cable winding machine.

[0015] Optionally, the machine body further includes an adjusting screw, which is rotatably connected to the surface of the base. The axis of the adjusting screw and the axis of the guide column are parallel to each other. The adjusting block is threadedly connected to the surface of the adjusting screw. The adjusting screw rotates and drives the adjusting block to slide along the axis of the guide column.

[0016] By adopting the above technical solution, the displacement of the adjusting block is precisely controlled by adjusting the lead screw, and the guide column provides a high-rigidity linear guide rail to restrict the rotational freedom of the adjusting block, thereby ensuring that the adjusting block moves only along the axial direction, which significantly improves the smoothness of the adjusting block's movement.

[0017] Optionally, the limiting ring is connected to a limiting component, which includes a limiting block and an elastic element. The inner wall of the limiting ring has a limiting cavity for the limiting block to slide. The sliding direction of the limiting block is perpendicular to the axis of the limiting ring. The surfaces of tension roller one and tension roller two are each provided with a plurality of limiting grooves for the end of the limiting block to be embedded. The inner wall of the limiting groove abuts against the surface of the limiting block to form a limit. One end of the elastic element in the elastic direction is connected to the inner wall of the limiting cavity, and the other end of the elastic element in the elastic direction is connected to the surface of the limiting block. The elastic element has a tendency to force the end of the limiting block to be embedded in the limiting groove.

[0018] By adopting the above technical solution, when the limiting ring is coaxially sleeved on the tension roller one or the outer circumferential surface of the tension roller one, and the limiting groove is connected to the limiting cavity, the elastic force of the elastic element one drives the limiting block to slide and embed towards the limiting groove. The surface of the limiting block abuts against the inner wall of the limiting groove and limits the limiting ring to the outer circumferential surface of the tension roller one or the tension roller two, realizing the detachable installation of the limiting ring. This facilitates the adjustment of the size of the limiting gap between two adjacent limiting rings, so that the limiting gap can be adapted to cables of different diameters, thereby improving the versatility of the winding machine.

[0019] Optionally, the end of the limiting block embedded in the limiting groove is provided with a guide surface. The guide surface is in the shape of a circular arc protrusion. The guide surface can abut against one surface of the tension roller or the second surface of the tension roller and guide the end of the limiting block to be embedded in the limiting groove.

[0020] By adopting the above technical solution, when the limiting ring approaches the limiting groove along the axis of tension roller one or tension roller two, the guide surface abuts against the surface of tension roller one or tension roller two and guides the end of the limiting block to be embedded in the limiting groove, thereby reducing the wear between the limiting block and tension roller one and extending the service life of the winding machine.

[0021] Optionally, the limiting component further includes a positioning ring and an elastic element two. The limiting ring has a positioning cavity coaxially formed on its surface for sliding. The sliding direction of the positioning ring is parallel to the axis of the limiting ring. The positioning cavity is connected to the limiting cavity. The limiting block has a positioning groove on its surface facing the positioning cavity for the end of the positioning ring to be embedded in. When the end of the limiting block is embedded in the limiting groove, the positioning groove is connected to the positioning cavity. One end of the elastic element two in the elastic direction is connected to the inner wall of the positioning cavity, and the other end of the elastic element two in the elastic direction is connected to the surface of the positioning ring. The elastic element two has the elastic force to drive the end of the positioning ring to be embedded in the positioning groove, and the surface of the positioning ring abuts against the inner wall of the positioning groove and limits the sliding of the limiting block.

[0022] By adopting the above technical solution, when the limiting cavity is connected to the limiting cavity, the elastic element one forces the end of the limiting block to be embedded in the limiting groove, the surface of the limiting block abuts against the inner wall of the limiting groove and limits the limiting ring to tension roller one or tension roller two. At the same time, the positioning groove is connected to the positioning cavity, the elastic element two forces the end of the positioning ring to be embedded in the positioning groove, the end face of the positioning ring abuts against the inner wall of the positioning groove and limits the sliding of the limiting block, thereby improving the connection stability between the limiting ring and tension roller one.

[0023] Optionally, the limiting component further includes multiple rollers, which are rotatably connected to the ring surface of the positioning ring at intervals around the axis of the positioning ring, and the rollers protrude from the wheel surface of the limiting ring and make rolling contact with the cable.

[0024] By adopting the above technical solution, the wheel surface of the roller protruding from the limiting ring makes rolling contact with the cable, and rolling friction replaces sliding friction, reducing wear on the cable and further extending the service life of the cable.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The setup of tension roller one and tension roller two, the combination of tension roller one and tension roller two is equivalent to a dual-mass damping system, which can filter high-frequency tension fluctuations, ensure that the cable tension remains smooth during braking, make the steel wire inside the cable less susceptible to micro-cracks caused by tension fluctuations, reduce fatigue damage to the cable, and thus extend the service life of the cable. The setting of the limiting ring disperses the inertial impact of the cable during braking to multiple limiting points, realizes the gradient adjustment of friction force, thereby suppressing the sudden tension of the cable and further improving the service life of the cable. The drive gear, transmission gear, and driven gear share the same axis of rotation, avoiding the need for additional bearings, couplings, or brackets required by a separate design, and significantly reducing the production cost of the cable winding machine.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a cable winding machine. (Refer to...) Figure 1 The cable winding machine includes a body 1 and a tensioning assembly 2. The body 1 includes a base 11, a guide column 12, an adjusting screw 13, and an adjusting block 14. The base 11 is provided with a tensioning cavity 15 and a guide cavity 16 spaced apart. The tensioning assembly 2 is installed on the inner wall of the tensioning cavity 15 and can maintain the tension of the cable. The inner wall of the tensioning cavity 15 away from the guide cavity 16 is provided with an inlet hole 17 for the cable to pass through. The axis of the inlet hole 17 is parallel to the length direction of the base 11. The inlet hole 17 passes through the outer wall of the base 11 along its own axis. A limiting frame 3 for placing the cable winding drum is installed on the surface of the base 11 near the inlet hole 17. The outer circumferential surface of the limiting frame 3 abuts against the inner wall of the cable winding drum to form a limit.

[0032] Reference Figure 1 The two ends of the guide post 12 along the axial direction are fixed to the inner walls of the guide cavity 16 facing each other. The axis of the guide post 12 and the height direction of the seat 11 are parallel to each other. The two ends of the adjusting screw 13 along the axial direction are rotatably connected to the inner walls of the guide cavity 16 facing each other. The axis of the adjusting screw 13 and the axis of the guide post 12 are parallel to each other. One end of the adjusting block 14 is slidably connected to the surface of the guide post 12. The sliding direction of the adjusting block 14 is parallel to the axis of the guide post 12. The other end of the adjusting block 14 is threadedly connected to the surface of the adjusting screw 13. The adjusting screw 13 rotates and drives the adjusting block 14 to slide along the axis of the guide post 12.

[0033] Reference Figure 1The end of the adjusting block 14 protruding from the seat 11 is provided with an outlet hole 18 for the cable to pass through. The axis of the outlet hole 18 and the axis of the inlet hole 17 are parallel to each other. The cable of the cable winding drum passes through the inlet hole 17 and the tensioning component 2 and is discharged from the outlet hole 18. The tensioning component 2 ensures that the cable tension remains smooth during the braking process, so that the steel wire inside the cable is not easily affected by tension fluctuations and micro-cracks are generated, reducing fatigue damage to the cable and thus extending the service life of the cable.

[0034] Reference Figure 1 The tensioning assembly 2 includes a tensioning roller 1 21, a tensioning roller 22, a driving gear 23, a driven gear 24, a transmission gear 25, and multiple limiting rings 26. The diameter of tensioning roller 1 21 is larger than the diameter of tensioning roller 22. Tensioning roller 1 21 and tensioning roller 22 are rotatably connected to the inner wall of the tensioning cavity 15 at intervals. The axis of tensioning roller 1 21 and the axis of tensioning roller 22 are parallel to each other, and the axis of tensioning roller 1 21 is parallel to the height direction of the seat 11.

[0035] Reference Figure 1 Tensioner roller 22 is located between inlet hole 17 and tensioner roller 21, and tensioner roller 21 and tensioner roller 22 are located on both sides of the axis of inlet hole 17. Multiple limiting rings 26 are divided into two groups. The inner rings of multiple limiting rings 26 in one group are connected at intervals along the axis of tensioner roller 21 to the outer circumference of tensioner roller 21. The inner rings of multiple limiting rings 26 in the other group are connected at intervals along the axis of tensioner roller 22 to the outer circumference of tensioner roller 22. The arrangement direction of the limiting rings 26 is parallel to the height direction of the base 11. The limiting rings 26 on tensioner roller 21 and the limiting rings 26 on tensioner roller 22 are staggered in the arrangement direction, and a limiting gap 262 is left between two adjacent limiting rings 26 for the cable to pass through.

[0036] Reference Figure 1The cable of the cable winding drum passes through the inlet hole 17, successively around the limiting gaps 262 on tension roller 1 21 and tension roller 2 22, and exits from the outlet hole 18. This requires the cable to undergo multiple directional changes during braking, rather than extending from the inlet hole 17 to the load end. Simultaneously, the elastic deformation of the cable is distributed across the bending sections of tension roller 1 21 and tension roller 2 22, rather than concentrated at a single location, reducing the risk of localized stress concentration. Furthermore, the diameter of tension roller 2 22 is smaller than that of tension roller 1 21, resulting in a smaller bending radius of the cable when passing over tension roller 2 22. This leads to a greater normal pressure and friction on the contact surface between the cable and tension roller 2 22, requiring the cable to overcome a larger static friction force to slide, thus limiting the initial speed of the cable. Conversely, the bending radius of the cable when passing over tension roller 1 21 is larger, resulting in relatively lower friction. As a secondary constraint, the tension roller 21 further attenuates cable movement. The additional resistance provided by tension roller 21 prevents a sudden drop in tension, making the combination of tension roller 21 and tension roller 22 equivalent to a dual-mass damping system. This system can filter high-frequency tension fluctuations, ensuring a smooth transition of cable tension during braking. This makes the steel wires inside the cable less susceptible to micro-cracks caused by tension fluctuations, reducing fatigue damage to the cable and extending its service life. At the same time, the two sets of limiting rings 26 are staggered in the arrangement direction, requiring the cable to pass through the limiting gaps 262 of tension roller 21 and tension roller 22 in sequence, forming an "S"-shaped zigzag path. This disperses the inertial impact of the cable during braking to multiple limiting points, achieving gradient adjustment of friction force, thereby suppressing sudden changes in cable tension and further improving the cable's service life.

[0037] Reference Figure 1 The driving gear 23 is coaxially fixed to the end of the tensioning roller 22, and the driven gear 24 is coaxially fixed to the end of the tensioning roller 21. The transmission gear 25 is rotatably connected to the inner wall of the tensioning cavity 15. The axis of the transmission gear 25 is parallel to the height direction of the seat 11. The transmission gear 25 is located between the driving gear 23 and the driven gear 24, and the transmission gear 25 meshes with the driving gear 23 and the driven gear 24.

[0038] Reference Figure 2 and Figure 3The limiting ring 26 is equipped with a limiting component 4, which allows the limiting ring 26 to be detachably mounted on tension roller 1 21 or tension roller 22. This enables the limiting gap 262 between tension roller 1 21 and tension roller 22 to be controllably adjusted according to the cable diameter, thereby improving the versatility of the winding machine. The limiting component 4 includes a limiting block 41, an elastic element 1 42, a positioning ring 43, an elastic element 2 44, and multiple rollers 45. The number of limiting blocks 41 and elastic elements 1 42 can be one, two, or more. In this embodiment, the limiting blocks 41 and... There are multiple elastic elements 42. The inner wall of the limiting ring 26 has multiple limiting cavities 261 evenly spaced around the axis of the limiting ring 26 for the limiting blocks 41 to slide. The sliding direction of the limiting blocks 41 is perpendicular to the axis of the limiting ring 26. The outer circumferential surfaces of the tension roller 1 21 and the tension roller 22 are each provided with multiple limiting grooves 211 for the ends of the limiting blocks 41 to be embedded. The inner wall of the limiting groove 211 abuts against the surface of the limiting block 41 and limits the limiting ring 26 on the tension roller 1 21 or the tension roller 22, so as to realize the detachable fixation of the limiting ring 26.

[0039] Reference Figure 2 and Figure 3 The elastic element 42 can be a compression spring or a tension spring. In this embodiment, the elastic element 42 is a compression spring with a certain deformation capability. The elastic element 42 corresponds to the limiting block 41. One end of the elastic element 42 in the elastic direction is connected to the inner wall of the limiting cavity 261, and the other end of the elastic element 42 in the elastic direction is connected to the surface of the limiting block 41. The elastic element 42 has the elastic force to drive the limiting block 41 to slide towards the limiting groove 211, and the end of the limiting block 41 tends to be embedded in the limiting groove 211. The end of the limiting block 41 located in the limiting groove 211 is provided with a guide surface 411. The guide surface 411 is in the shape of a circular arc protrusion. The guide surface 411 can abut against the surface of the tension roller 21 or the tension roller 22 and guide the end of the limiting block 41 to be embedded in the limiting groove 211, thereby reducing the wear on the limiting block 41 and extending the service life of the winding machine.

[0040] Reference Figure 2 and Figure 3The limiting ring 26 has a positioning cavity 263 coaxially formed on its annular surface for the positioning ring 43 to slide. The sliding direction of the positioning ring 43 is parallel to the axis of the limiting ring 26. The positioning cavity 263 connects to multiple limiting cavities 261. The limiting block 41 has a positioning groove 412 on its surface facing the positioning cavity 263 for the end of the positioning ring 43 to be embedded. When the end of the limiting block 41 is embedded in the limiting groove 211, the positioning cavity 263 connects to the positioning groove 412. The elastic element 44 can be a compression spring or a tension spring. In this embodiment, the elastic element 44 is a compression spring with a certain deformation capability. One end of the elastic element 44 in the elastic direction is connected to the inner wall of the positioning cavity 263, and the other end of the elastic element 44 in the elastic direction is connected to the annular surface of the positioning ring 43. The elastic element 44 has the elastic force to drive the end of the positioning ring 43 to be embedded in the positioning groove 412, and the inner wall of the positioning groove 412 abuts against the surface of the positioning ring 43 and limits the sliding of the limiting block 41.

[0041] Reference Figure 2 and Figure 3 When the limiting ring 26 slides along the axis of the clamping roller towards the limiting groove 211, and the limiting groove 211 is connected to the limiting cavity 261, the elastic element 42 forces the limiting block 41 to slide towards the limiting groove 211, and the end of the limiting block 41 is embedded in the limiting groove 211; at the same time, the positioning cavity 263 is connected to the positioning groove 412, and the elastic element 44 forces the positioning ring 43 to slide towards the positioning groove 412, and the end of the positioning ring 43 is embedded in the positioning groove 412. The inner wall of the positioning groove 412 abuts against the surface of the positioning ring 43 and limits the sliding of the limiting block 41, thereby improving the limiting stability of the limiting ring 26 on the tensioning roller 21.

[0042] Reference Figure 2 and Figure 3 Multiple rollers 45 are evenly rotated around the axis of the positioning ring 43 and connected to the ring surface of the positioning ring 43. The axis of the positioning ring 43 and the axis of the rollers 45 are perpendicular to each other, and the wheel surface of the rollers 45 protruding from the limiting ring 26 makes rolling contact with the cable. Rolling friction replaces sliding friction, thereby reducing wear on the cable and extending the service life of the cable.

[0043] The implementation principle of a cable winding machine according to an embodiment of this application is as follows: the cable of the cable winding drum passes through the inlet hole 17, successively around the limiting gap 262 on tension roller 1 21 and the limiting gap 262 on tension roller 22, and is discharged from the outlet hole 18. This causes the cable to undergo multiple directional changes during braking, rather than the diameter extending from the inlet hole 17 to the load end. At the same time, the elastic deformation of the cable is distributed to the bending sections of tension roller 1 21 and tension roller 2 22, rather than concentrated at a single location, reducing the risk of local stress concentration in the cable. Furthermore, the diameter of tension roller 2 22 is smaller than that of tension roller 1 21, resulting in a smaller bending radius of the cable when passing over tension roller 2 22. The normal pressure on the contact surface between the cable and tension roller 2 22 is relatively large, and the friction is greater. The cable needs to overcome a large static friction force to slide, thereby limiting the initial movement speed of the cable. The cable bends when passing over tension roller 1 21. With a large radius and relatively low friction, the tension roller 21 acts as a second-level constraint, further attenuating cable movement. The additional resistance provided by tension roller 21 prevents a sudden drop in tension, making the combination of tension roller 21 and tension roller 22 equivalent to a dual-mass damping system. This system can filter high-frequency tension fluctuations, ensuring a smooth transition of cable tension during braking. This prevents the steel wires inside the cable from developing micro-cracks due to tension fluctuations, reducing fatigue damage to the cable and extending its service life. Simultaneously, the two sets of limiting rings 26 are staggered in their arrangement direction, requiring the cable to sequentially pass through the limiting gaps 262 of tension roller 21 and tension roller 22, forming an "S"-shaped zigzag path. This disperses the inertial impact of the cable during braking to multiple limiting points, achieving gradient adjustment of friction and suppressing sudden changes in cable tension, further improving the cable's service life.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
